Tips for Better Kids' Sleep

routine

Consistent Bedtime Routine

A predictable sequence of calming activities signals the brain that sleep is coming. Aim for 20-30 minutes of wind-down time.

No Screens 1 Hour Before Bed

Blue light from screens suppresses melatonin production. Switch to books, puzzles, or quiet play before bedtime.

thermostat

Cool, Dark Bedroom

Keep the room between 65-70°F (18-21°C). Use blackout curtains and a nightlight only if needed for comfort.

Regular Exercise During the Day

Active play and physical activity help children fall asleep faster and sleep more deeply. Avoid vigorous exercise close to bedtime.

FAQ

How much sleep does a 2-year-old need? expand_more

A 2-year-old typically needs 11–14 hours of total sleep per day, including one daytime nap of 1–3 hours. Most toddlers do well with a bedtime between 7:00 and 8:00 PM and a wake time around 6:00–7:00 AM.

Should my child have a fixed wake-up time? expand_more

Yes. A consistent wake-up time — even on weekends — is the single most powerful anchor for a child's circadian rhythm. It regulates sleepiness at bedtime and improves overall sleep quality. Try to keep the wake time within 30 minutes of the weekday schedule.

When should my child stop napping? expand_more

Most children naturally drop their nap between ages 3 and 5. Signs your child is ready include consistently resisting the nap, taking longer than 20 minutes to fall asleep at nap time, or the nap pushing bedtime too late. Replace the nap with a quiet rest period to ease the transition.

Why does my teenager stay up so late? expand_more

During puberty, the brain's internal clock shifts later by 1–2 hours — a biological change called "sleep phase delay." Teens genuinely don't feel sleepy until later at night. Combine this with early school start times, and most teens are chronically sleep-deprived. Limiting screens before bed and keeping a consistent schedule can help.

How does screen time affect my child's sleep? expand_more

Screens emit blue light that suppresses melatonin production, making it harder to fall asleep. Beyond the light, stimulating content (games, social media, exciting videos) keeps the brain alert. The American Academy of Pediatrics recommends no screens for at least 1 hour before bedtime for all ages.
